MOLD FOR FOB/KING SAXOPHONE MOUTHPIECES.

Application lcd June 10, 1922. Serial No, 567,312. I

To all whom t may concern:

Be itknown that I, ARCHIBALD P. Gm- I-IAM, a citizen of the United States, residing at Elkhorn, in the county of Valwoprth and State of Wisconsin, have invented new and useful Improvements in Molds for Forming Saxophone Mouthpieces, of which the following is a specification.

This invention relates to saxophone mouthpieces and the Ina-nner of forming them.

Heretofore it has been the practice to turn l' out the mouthpieces for saxophones, on

'i drawings wherein lathes, or analogous machines, making the mouthpieces quite expensive and requiring considerable time and labor for properly shaping them, and it is an object of this invention lto provide suitable molds and cores by means of which the mouthpieces may be formed by the die casting process, thereby materially decreasing the expense contingent -with the forming of the mouth piece as Well as resulting in savings in time and labor.

Another object of this invention is to provide a saxophone mouthpiece as specified which has a separate sleeve inserted in a portion of the body at its outlet end for constricting ,the outlet and particularly adapting the mouthpiece for construction by die casting. y

A still further object of the invention is to provide a novel forml of core and plunger structure particularly designed tofaclitate the die casting ofthe' mouthpieces and con-l structed to maintain absolute accuracy in the molding of the mouthpieces.

Qther objects of ,the invention will appear-inthe following detailed description.

Fig. 6 is a cross section taken on the line (3-6 ofFig. 5j

Fig. 7 is a view partly'in section and partly 'inside elevation offa saxophone I mouthpiece constructed in accordance with this invention. y

Referring more particularly to the drawings, a saxophone mouthpiece` 1, is shown, which saxophone mouthpiece is-die cast, of hard rubber, bakelte, or analogous material such as commonly used in the construction of mouthpieces for saxophones and in forming the mouthpiece 1, a mold 2 of any approved type, or construction such as used in die casting, is utilized; which mold is provided with a chamber 3 properly 'shaped to provide the desired configuration to. the4 mouthpiece 1, having the flat surface 4 to provide the deck or face 5 of the mouthpiece l, and further provided4 with the rounded relatively large portion 6 for providing the rest of the mouthpiece. The bore or inner coniguration of the mouth iece 1 is provided b-y the use of a core which is constructed preferably of brass ork'analogous met-al and has a substanially-- cylindrical portion 8 whichis carried by the handle portion 9, and as clearly shown in Fig. 1` of the drawings the substantially cylindrical portion 8 gradually increases in diameter towards the handle portion 9 so as to permitv the easy withdrawal of the core 7; from.

throat 10 of the mouthpiece 1 .is lformed byl a plunger 11 which is constructed of brass or analogous material and is shaped, in plan, I

drawings as clearly yshown in Fig. 4 of the y kkthroat 10.`

to provide the desired shape to th kThe corner. 12 of the plunger 11 .is beveled slightly 'as clearly shownfin ythe drawingsf" so as to provide. the proper 4'shap`e .to the finner wall of thegthrvoatlat itsfo'penedge and for proper alignment with theinclined edge 13 of the reduced throat forming end 14 of the core 7. The upper surface of the reduced throat forming end ofthe core 7 is flat, and the plunger 11 rests thereon during the molding of the mouthpiece 1.

- lt is to be understood that in constructing the core 7 and plunger 11 that proper allowance is made for' shrinkage in the material of which the mouthpiece is formed as is usual in the construction of patterns.

It isl necessary, to obtain the proper results from the mouthpiece that the outlet end of the bore 15 of the mouthpiece be of smaller diameter than the inlet end and it `will be readily understood that should the core 7 be constructed to provide this reduced size of the bore it would be impossible to withdraw the core after the mouthpiece had been formed, and to provide lthis reduced size of the bore, a sleeve 17 is provided the bore of which is of uniform diameter throughout While the outer diameter of the sleeve gradually increases towards one end, as clearly shown in Fig, of the drawings so as to permit the sleeve to properly fit in the bore of the mouthpiece l. The sleeve 16 may likewise be formed by die casting utilizing a mold 17 through which a cylindrical core 18 is inserted as shown in Figs.

5 and 6 of the drawings.

From the foregoing description taken in connection with the accompanying drawings it will be apparent that a saxophone mouthpiece has been provided which will particudie casting process thereby permitting the construction of the mouthpieces Iat a much lower cost and with much less labor than it is/possible to produce them by turning or the present approved method of constructing them.
